ZHCSLP7C December 2019 – February 2021 TPD4S311 , TPD4S311A
PRODUCTION DATA
In this application example we study the protection requirements for a full-featured USB Type-C DRP Port, fully equipped with USB-PD, USB2.0, USB3.0, Display Port, and 100 W charging. The TPS65982 is used to easily enable a full-featured port with a single chip solution. In this application, all the pins of the USB Type-C connector are used. Both the CC and SBU pins are susceptible to shorting to the VBUS pin. With 100 W charging, VBUS operates at 20 V, requiring the CC and SBU pins to tolerate 20-VDC. With these protection requirements present for the USB Type-C connector, the TPD4S311 is used. The TPD4S311 is a single chip solution that provides all the required protection for the SBU and CC pins in the USB Type-C connector.
Table 9-1 lists the TPD4S311 design parameters.
DESIGN PARAMETER | EXAMPLE VALUE |
